More recent discoveries by Kennett, with his students and colleagues, result from studies of a late Quaternary stratigraphic sequence in Santa Barbara Basin. This sequence is providing a record of climate change of very high stratigraphic resolution, perhaps the highest in the world ocean. Hence, important components of the climate system have been revealed that are not seen in other sequences.
Also, over the last few years Kennett, with his many colleagues, has been addressing the question as to whether a major cosmic impact at 12.9 ka led to abrupt cooling at the onset of the Younger Dryas episode, north American megafaunal extinction and human cultural and population change.
